> I don't think I've met a single one around my age (early 30's, late 20's) who didn't start when they were young.

This is probably partly confirmation basis and partly insufficient data. I doubt every time you meet a fellow developer you ask them how old they were when they first started programming.

I'm 35 and didn't start coding until about four years ago (when I decided to go back to school and switch careers) - there's another dev on my team that started even later, and I know several that never wrote a line of code before college. So yeah we're out there.
